LOG-CHAIN.

Specification of Letters Patent.

Patented Julie 6, 19 il Application filed April 28, 1910. Serial No.558,249.

To all whom 'it may concern:

Be it known that I, ALFRED X. MILLER, a citizen of the United States,residing at Marinette, in the county of Marinette and State ofWisconsin, have invented certain new and useful Improvements in Log-Chains, of which the following is a speci cation.

This invention relates to trip hooks for7 logging chains and has for itsobject the provision of a comparatively simple and thoroughly efficientdevice of this character, by means of which a chain or other flexiblebinding element may be securely fastened around a number of logs orother load so as to prevent accidental separation thereof duringtransportation or shipment.

A further object is to provide a trip hook, the construction of which issuch that the same may be used as a chain tightener.

A further object is to provide a hook having a binding chain secured toone end thereof and provided with a trip link adapted to embrace theshank' of said hook, means being provided for tripping the link, therebyto release the hookwhen it is desired to dump the load of logs.

A still further object of the invention is generally to improve thisclass of devices, so as to increase their utility, durability andeiliciency.

Further objects and advantages will appear in the following description,it being understood that various changes in form, proportions and minordetails of const-ruction may be resorted to within the scope of theappended claims.

For a full understanding of the invention and the merits thereof andalso to acquire a knowledge of the details of construction, reference isto be had to the following description and accompanying drawings, inwhich:

Figure 1 is a side elevation of a trip hook constructed in accordancewith my invention, showing the same in position on a load of logs, theshank .of the lever being in position to be swung downwardly forengagement with the trip link; Fig. 2 is a similar view, showing thetrip link in engagement with the shank of the hook; Fig. 3 is aperspective view o f'one of the hooks sho-wing the binding elementattached thereto.

Corresponding and like parts are-referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

yaround a load of logs,

duce an intermediate slot 9 for engagement Y with one of the links of achain or other binding element, indicated at 10. The head 6 isv providedwith a lateral enlargement 11 having an opening 12 formed therein andpreferably disposed slightly7 above the closed end of the slot 9 forengagement with a portion of the binding element or chain 10. Secured tothe chain 10V is a trip link 1l adapted to embrace the shank 8 of thehook when the latter is swung downwardly to the position shown in Fig. 2of the drawings, thus to hold the hook against tilting movement. Thelower end of the shank 8 is provided with an offset portion 15 whichserves to assist in preventing accidental. displacement of the link 14,there being an opening 16 formed in the shank opposite ythe offsetportion 15 thereof for the reception o a locking key 17 The locking key17 is preferably formed from a single length of spring wire, one end ofwhich is bent to produce a coil, while the other end thereof isformedwith an eye 18 for engagement with the adjacent end of a shortchain sect-ion 19, the other end of the chain 19 being 'secured to oneof the links of the chain 10, as best shown in Fig. 3 of the drawings.

-In operation, the chain 10 is passed indicated at 21 and the shank 8 ofthe hook grasped in the right hand and said hook moved upwardly untilthe bill thereof engages one of the links of the binding element, saidlink being inserted in the slot 9, as best shown in Fig. 1 of thedrawings. lThe operator then exerts a downward pressure on the shank Swhich causes lthe lower lor perforated end of the shank to assume aposition substantially parallel with one end of the chain 10,' and atthesame time exert a longitudinal pull on the other end thereof so as totighten the chain and cause said chain tov eifectually grip the load oflogs. The trip link 14 is then passed over the free end of the shank 8,after which the locking key 17 is introduced in the opening 1G and inwhich position, the hook will be securely held against tilting movementduring transportation or shipment of the logs, as best shown in Fig.

2 "of the drawings. In order to dump the logs, it is merely necessary todetach the key 17 from the opening 16 in the shank of the hook and placethe hooked end of an ordinary trip chainj around the shank 8 or againstthe' link-'111i and exert a slight longitudinal pull thereon which4disengages thel trip link lelfroin said shank and causes the llatter tomove upwardly in the arcof a circle,fso as to cause the chain l0 to slipout of 'the slot 9,- thusreleasing the logs and allowing the same v-tobe deposited on the ground. y

-I Attention ishere called'to the fact that the opening lf'is4 disposedin a plane slightly above the closed end of the slot 9 so as to insureatrip action of the hook 5, while the offset portion or enlargement onthe shank,

by engagement with thevlink' 14:, serves to vprevent said linkfromslipping' longitudinaliy on the shank of the hook when 'fthe locking key17 is detached and until a slight downward ressure is exerted on saidlink 4 by means o the chain 20. Such a construction prevents `prematurerelease of` the hook when theoperator removes the key 17 so as'effectually'to prevent the logs from falling on the operator when'walking around `the load preparatory to Ldumping the same. It willroztcourse be understood that the binding eiementmay be made iny one or more"sections, the mainobject of the device being element together so as'toto draw the adjacent ends of said "binding A prevent accidentaldisplacement of the load.

Having thus described the invention, what is claimed as new is: v l. Adevice of the class described includingf abi-riding element, a hooksecured to one portion of thebinding element and adapted to engageanother portion "thereof, a vlink carried by said binding element andadapted tov embrace the shank of the hook, and a locking key extendedthrough the free endl of the shank beneath the link for preventingaccidental displacement of said link.

2. A device of the ciass described includi ing a binding Chain, a .hooksecured to one portion of the chain and provided-1 with a slot adaptedto receive one of the links of said chain, a trip link carried by thechain and Vadapted to embrace the shank of thej hook,"a-nd a locking keyengaging the lower end of the shank. t 1 I device of the class describedincluding abinding chain, a hook secured to one portion of the chain andprovided with a bill spaced from the. shank of the hook to form aslottor engagement with one of the links of said chain, therebeing anenlargement formed on the shank oi the hook, a trip linkcarried bythe-chain and adapted to embrace the shank of the hook at saidenlargement, and a 'locking member extending transversely through anopening in the shank oit" the hook at said enlargement.

4. A device .pf the class described-including a binding chain, a hookhaving-an enlarged head provided with anopeninglfor the reception ot'.one of the links of the binding chain and having its bill spaced fromthe shank of the hook to form a slot for engagement with another link ofsaid binding chain, the opening in the headbeing disposed in a planeabove the-closed end of the slot, there being an enlargement formed onone lside of the shankof the hook at the lower end thereof, a trip linkcarriedy by the binding chain and Iadapted to embrace the shank of thehook at said enlargement., a locking key extending through the opening`in the shank of the hook at the enlargement, and a connection betweenthelocking key and the binding chain.,`

5. A device of the class described includ- 'ing a binding chain, a hooksecured to one port-ion of the binding chain and provided vwith aperforated shank and an overhang- .ing bill spaced Jfrom the shank toform a slot
